AK suppressors

[Duce]

The AWB includes threaded barrels.
Well after the Sept-14 sunset we will be able to have threaded barrels again.
So i was wondering if any of you guys have see any suppressors that will fit on an AK. I have a Sar-1. And was hoping to buy a suppressor before the sunset.
Ive heard of a company called reflex but have never heard of any prices.
Anyone have a cheap source?
And would i have to replace the barrel, or get it threaded?

You can't own a suppressor unless you file a $200 tax form with the ATF (AND get it approved with a CLEO signature.) Also, the 7.62x39 is not a sub-sonic round (its faster than speed of sound) so you still get a good crack out of the rifle...

For the 7.62x39 and 5.45x39

You're right, you'll get the sonic crack from the bullet. You can suppress the sound of the rifle, so it's location remains unknown.

You can legally make a suppressor if you apply for a permit before starting. It costs $200 and is similar to the FA permit, but suppressors are legal. On the other hand, proper shaping of the baffles is difficult, and they have to be held in place against some pretty strong pressures. And they have to be aligned so the bullet passes through them without touching. You can make flat disk baffles (like a washer), but they are inefficient and the suppressor would be much larger or louder.

I dont think i have the know how to make a suppressor. But thanks
This is a pic of the reflex suppressor.
They say you dont have to use subsonic ammo. Even tho it helps.

So is $550 a good price?
I know its cheap for an NFA but are there any cheaper ones out there?

[Packrat]

Suppressors are generally pretty expensive, especially the ones that don't use "wipes" (soft material that the bullet passes through, which wears out quickly), but I don't know how expensive. It's more than I would pay, certainly.

The good thing about suppressors that use wipes is that you can easily replace the worn out materials yourself with inexpensive parts and materials (even a novice can do it, supposedly), rather than having to send it to a licensed manufacturer for repair.

For pistols, suppressors seem to be inexpensive...a MAC suppressor is about $200-$300 (before tax) on average. Not so for rifles.

I didn’t know you were able to keep extra wipes on hand, I thought the ATFe frowned on that.

If/when the AWB goes away I’d really like to pick up one each of the AAC cans in the two calibers. From what I understand, AAC builds a reputable product and I think the AK would be a fun platform to suppress.

This according to a post on http://www.mac10.org/ :


Wipes are NOT considered suppressor parts, and as such, can be replaced by the owner. There is an ATF letter on file that will back this up. All other parts, such as baffles, end caps and tubes have to be replaced by a C2. You will need polyurethane or neoprene with a durometer of at least 90, shore A. You can order the round stock and simply cut your own "slices" and punch the center hole. It's a lot cheaper than buying them. Mcmaster-Carr is a good source of material, or any rubber supply company will do.



As Erik said, RPB sells a die. You buy the neoprene, set the die on it, hit it with a hammer, have new wipe.

Alternative: send it to Gemtech. They will replace the internals with wipeless upgrade for $125 that will be quieter than wipes.


I haven't seen the suggested ATF letter. Maybe I'm right, maybe I'm wrong. I'll try to look it up, but as always, don't take a random forum poster's word for it...research it yourself.

Found it!

In regard to the two parts in your cited example, we consider a
baffle to be a silencer, but a wipe, which is usually nothing more
than a rubber or plastic disc with a hole in it, is generally not
considered to be a silencer. Thus an individual owner could
replace a wipe.

An example of different ideas on firearms: in Finland you can buy suppressors in any hardware store for about $20. They aren't required, but are considered an indication of a thoughtful shooter who doesn't want to disturb others. That's probably the reason Finland has such a high level of gun violence. They're saved only by the fact that it's hard to do a drive-by with reindeer.

So if I went to Finland would they sellme a supressor?

FAC has a fake one for the AK if you just want the look.

[Packrat]

One of the wonderful ideas which never panned out was to get a Turkish Mauser (at that time, $35), replace the barrel with about 10" of .45 barrel (chambered for .45 ACP), and hack out a space in the magazine that would accept a Colt Gov't magazine (and feed from it). Now that would be a real rifle to suppress! Or convert a Saiga .410 to chamber .44 Spl (which would have to be through a rifled barrel) and put a reflex suppressor on it, with the first chamber starting at the gas block. Again, a serious rifle.

Using a supersonic bullet with a suppressor will suppress the sound of the cartridge firing (you only need to get it quieter that the AK action; you can't suppress that, either) but the target (if living) will hear the sonic crack of the bullet as it passes. (So hit it and kill it, don't miss!) There will be no boom of the cartridge firing, so on animals that aren't used to being shot at will often stop and listen rather than being spooked by the sound. I've heard that people who are shot at (and missed) learn to be alerted by the crack so they are listening for the rifle sound when it reaches them a fraction of a second later. I've never been shot at and missed, so I can't verify that.

[Sammoh]

So you've been shot at and hit?

[Packrat]

Sammoh, one of the reasons I gave up the 9mm (and went back to the .45 ACP) was that an acquaintance went shooting and wanted to fire my P.38. The first shot was OK, but as he was handing it to another shooter he squeezed the (now single-action) trigger and put a FMJ into my leg about 3" above the knee. My first thought was that I had felt the muzzle blast; then that he had come so close that he had ripped by pants; then (so help me) that he had shot through the pants (because I could now see 2 holes) WITHOUT HITTING ME! About that time logic took over and I realized that there was no way he could have shot through the pants without a piece of the leg being in the way, but I couldn't believe I was really hit till I looked at the hole in my leg. (We bandaged it with 2 handkerchiefs and I walked 5 miles home on it. I'm not that tough; it never developed more than a dull ache, about like a bruise.) At that time in that school students were not allowed guns or cars, so we walked to where we could shoot. I could do without a car, but without a gun? Never! (That P.38 also was the major contributor to a case of tinnitus that allows me to hear the insect sounds of a Midwest summer night all year round.)

The company is called BR-Tuote ("BR Products")

Here's a direct link to the AK suppressor page:

Here in Finland they cost about $200.

[stg58guy]

So if I went to Finland would they sellme a supressor?


Sure. Permits are required for complete firearms, barrels and "locking devices" such as bolts. Anything else can be bought and owned by anyone.
To buy cartridges, primers and powder you need a permit for a suitable gun - or a permit that allows you to borrow a gun for which they could be used.

I'm slightly afraid that not everybody is going to notice you're being humoristic here... Despite the reindeer. :D

I think I've actually seen a live reindeer. When I was a kid. In a zoo. Never been to Lapland.

Just a note, but I've been thinking of one like this a while, and Rhineland Arms makes them;

I've got a .45 suppressor on order anyway, so still thinking...

[USMC 0341]

My $0.02 on this subject - go for the wipeless suppressor if it is a choice.

I have a registered suppressor for a 45ACP MAC10 - this is an early RPB can with wipes. Yes, as long as the wipes are fresh it does a great job. But once the wipes wear out it does practically nothing. Even as big as these cans are and as relatively small as the powder charge in a 45 is once the wipes go I just unscrew the can and put it aside.

The wipes only last about 2 to 3 magazines - and this is with slow 45 ACP rounds. I would expect that fast moving 7.62 or 5.45 rounds would chew up the wipes much faster. In addition, these lighter rounds pushing through the wipes would probably be keyholing and you'd be lucky to keep them on the paper at 50 yards.

One great thing about doing this with the 7.62 is that there are plenty of nice, heavy 30 caliber bullets which you could load to sub-sonic speeds and still have plenty of power downrange.

[Packrat]

I've talked to a few hand-loaders, and their observations agree with mine: .308 bullets have no problem with the larger bore diameter. They spin just fine, even if they are .002 or .003 too small.

At one time I had some information from a writer in Finland about loads he and others had worked on that were "silent with out suppressor (swos)", I think they were called. They used heavy bullets and light loads, but got some loads that were effective. I've never run across the concept since.
